The ETH-255 is a two channel combination transducer and ECG/EMG amplifier used in teaching student physiology and research labs. The front panel is divided into two identical functioning units, capable of making low noise AC coupled recordings of bioelectric potentials or DC coupled transducer recordings. the four knobs control each channel, the functions of which are High-pass, Low pass Fliters, Gain Control, and Input Offset. The rear panel connects the input transducers and digital output to a computer data acquisition system. For detailed information please refer to the operation manual.
